dissipated by the existence of a living specimen brought from the 

 Cape of Good Hope, according in every particular with Le Vail- 

 lant's description of" the Oricou, and fiaving the remarkable folds of 

 skin which pass up the sides o( the neck and roiind the ears developed 

 even to agreaterextent ihaii is representt-d in hisfigure. A specimen 

 of the Pondichery Vulture ( Vultur Ponticerinnus, Daud.), the only 

 other species in vvhich the naked neck hason each side a longitudi- 

 nal fold of skin, was laid on the table : and it was pointed out that 

 in this bird the fold of skin terniinates an inch belovv the opening 

 of the ear, vvhile in the Sociable Vulture it passes upwards and sur- 

 rounds the upper part of the ear; and that the breastftathers of 

 the Pondickery Vulture are short and rounded, whiie those of the 

 Sociable Vulture are very long and somevvhat sabre-shaped. 



Mr. Gray stated, that since M. Kuppel's Monograph was written, 

 he had apprised that scientific traveiler, in answer to his previous 

 inąuiries on the subject, that a specimen of another vulture rejected 

 by him as a doubtful species (the Vultur Angolensis, Lath.) exists 

 in the British Museum, to which it was presented on the return of 

 the unfortunate expedition up the river Congo. 



Mr. Owen resunied the reading of his Memoir on the Anatomy of 

 the Orang Utan {Simia Satyrus, L.), portions of which had been 

 communicated by him to the Committee at several of its previous 

 Meetings. On this occasion he limited himseK to the myology of 

 the lower extremities. 



He commenced by remarking, that no anatoniist can contemplate 

 the lower extreaiity of a .iuadrumanous animai, or experience the 

 degree of mobiUty orwhich the several parts of it are susceptible in 

 the living or undissected body, with()ut being prepared to find cor- 

 responding modifications of the muscular system and conseąuent de- 

 viations from the structure of these parts ms they exist in man. It is 

 accordingly in this part of the boily that the most remarkable difFe- 

 rences in the (orms, proportions, and attachments of the museles are 

 found to obtain betvveen the ape and the human subject; and it will 

 Jiot therefore be niatter of surprise lo fiiul, that in the Orang Utan, 

 whose inferior exireriiities, from their shortness and flexibility, are 

 so well adapted to the vanous agiie movements of a climber, there 

 exists a high degree of this deviation from the human structure, 

 and an approximation, in some measure symmetrical, to the arrange- 

 ment of the moving powers in the upper extremity. Variations of 

 more or less consequence occur, indeed, so freąuently as to render 

 it necesčiary to consider the whole of the museles seriatim ; and 

 each of them was accordingly dtscribed separately as regarded 

 its attachn)ents, foim, and relative position. These details are 

 necessarily abridged in the present abstract, except as regards 

 the museles of the hinder hands, vvhich require a developed notice 

 to render their structure intelligible. 



The glutcBus magnus is a thin narrow musele, inserted lower down 

 the thigh bone, and having a more posterior origin than in man : 

 its extent of action is consequently increased, though its strength
